 * 2) Behind the red door, to the left there's a vent, go through it to find a flemoidus commonus, a chex armor and a bowl of vegetables. (sector 191)

Non-Official

 * 1) To the left of the yellow key room there's an openable wall that acts as a shortcut on both ways so you won't have to open the three doors.
